Within this article we will take a closer look at the technical specifications of the Z27s monitor from HP. For this we will talk about all possible categories that could be relevant. To start with, we will look at the display, talk about the design and in the next section we will go into the features of the monitor. Other features such as power consumption, connectors and certifications will follow later in the text.
Display
Let's start with the most important component of a monitor, the display. Depending on the aspect ratio of height and width, monitors can be rather wide or square, for example. Besides the pure physical dimensions, the resolution of the display and thus the quality of the display is also decisive here. For easy comparability, however, screen sizes are usually given in inches. This unit of measurement simply compares the diagonal length from the lower left to the upper right corner of the display and is thus universally applicable. This device has a screen diagonal of 27 inches ( 68.5 cm on the diagonal). Let's keep it short and sweet. The monitor has an aspect ratio of 1.778 : 1. Approximately 86.3 % of the front of the monitor is taken up by the display, while the remaining area consists of screen edges that cannot display any image information. If you want to set up several monitors next to each other, it is advisable to choose monitors with narrow edges. The display is a AHVA panel. The panel has a resolution of 3840 x 2160 px. The pixel density is 163 ppi. The pixel pitch is 0.155 mm. The continuous possible brightness specified by the manufacturer HP is 300 nt. The panel is illuminated by W-LED. The built-in panel ensures stable color reproduction of the image, even at deviating viewing angles, by means of its 178 ° (horizontal) viewing angle. HP promises stable color reproduction moreover within a 178 ° vertical angle. The refresh rate is horizontally seen at the Z27s 30 khz to 135 khz. Vertically, however, the image renews at a minimum rate of 24 hz up to 60 hz. The minimum response time of the monitor is ms. The average response time of the monitor is about ms. The display panel is Anti-glare/Matte (3H).
Color space
The panel has a bit depth of 10 per color channel, but what does that mean? The number of bits determines how many colors can be encoded for the individual pixels of the display. For an 8-bit panel, for example, this is 256 different colors (2^8 = 256). However, since we usually display three different colors per pixel at the same time, in theory about 16 million (256^3) different colors are possible by mixing the three pixels. A 10-bit panel could even display a billion colors. According to the manufacturer, the coverage of the SRGB color space is 100 %.
Contrast ratio
Contrast ratio is a common measurement used to represent the maximum relative differences in brightness between black and white. It describes the ability of a screen or projector to produce a high-contrast image and is the quotient of the maximum and minimum displayable luminance. The higher the values are away from each other, the stronger the quantitatively seen difference between black and white is set up, which in turn results in an improved image quality. This monitor from HP has a static contrast ratio of 1000 : 1 , according to the manufacturer. In contrast to the static contrast ratio, the dynamic contrast ratio changes the brightness of the panel itself in addition to the difference measurement from black to white. In addition to the difference between the brightest and the darkest pixel, the backlight is thus changed. Since the brightness of the panel may not be able to be adjusted exactly to a single pixel, a so-called halo effect is possible. The value of 5000000 : 1 of dynamic contrast ratio for the monitor Z27s cannot provide any information about the severity of the halo effect here. Therefore, it is more useful to compare the static contrast ratio.

The monitor supports all HDR modes listed here:
screen design
For the installation of the monitor, a space requirement of approximately 37 cm in height, 62.5 cm in width and 6 cm in depth is to be assumed.
The size of the Z27s on the desk is likely to be particularly relevant for most users. HP specifies a space requirement of 53.5 x 62.5 x 24.2 cm (HxWxD) with the included stand. As for the weight, HP states a total weight of 7.8 kg with stand. The monitor Z27s without the stand weighs 5.4 kg. This weight reduction should be taken into account for wall or arm mounting, since monitor arms have a maximum load capacity. Speaking of weight without a stand and thus wall or table mounts. The monitor supports a Vesa mounting. A height-adjustable stand ensures an improved ergonomic posture during use. The monitor can be moved to a maximum height of 12 cm. This value is always measured from the bottom edge of the screen.
Rotate, tilt and swivel
The monitor from HP has a pivot function and can thus be rotated using the included stand. A rotation to the left is possible with up to 0 degree. To the right, the monitor can be rotated by 90 degree. The Z27s can be swiveled when mounted on the included stand. Pivoting to the left is possible up to 45 degree. Pivoting to the right is possible up to 45 degree. The tilt of the monitor Z27s can be individually adjusted to optimize the viewing angle and increase comfort during use. The angle of inclination to the rear is 20. The monitor can be tilted forward by 5 degree.

Features
Panel manufacturer
Many manufacturers of monitors and TVs fall back on third-party manufacturers, such as Samsung or LG, when choosing the actual display (panel). Thus, many of the monitors have the same panel and, conversely, differ only in their design, additional functionalities, the software used and, of course, the price. Two monitors from HP or another manufacturer with an identical panel do not necessarily have to have the same picture quality, but it is usually a first indicator for a purchase decision. The panel used here is originally from AU Optronics and has the model number M270QAN01.1.
WiFi / Bluetooth
Power consumption
On average, the monitor consumes approximately 71 w. The maximum power consumption (peak) specified for this monitor is 91 w. In standby mode, the device consumes approximately 0.8 w. When switched off, on the other hand, the monitor consumes only 0.2 w. In ECO mode, the monitor consumes 25 w. The monitor can be operated on a 110v power supply. The monitor can be operated on a 220v power supply. The power grid has to supply a frequency of 50 hz to 60 hz.
Environment
The maximum height at which the monitor may be operated, according to the manufacturer's specifications, is 5 km. For temperature, the maximum permissible ambient temperature is 35 °C. Below a temperature of 5 °C , the monitor from HP should again not be used. The humidity must not exceed 80 percent. At least, however, 20 percent humidity. The monitor may be stored at a maximum humidity of 95 percent. The minimum humidity during storage should not fall below 5 percent. The maximum storage temperature should be according to HP 60 °C. Minimal were given by HP -34 °C. According to the manufacturer, the monitor may be stored at a maximum height of 12.192 km.
Packaging
The monitor is packaged in a cardboard box measuring 49.1 x 71.8 x 30.2 cm (height x width x depth). The box together with the monitor weighs about 10.2 kg.
